Builds the connection between app profile and existing self-tests.

Component 3:

The test kits


Selected reliable self tests are already 3EP Flex ready.

... and how they work together

The digital 3EP self-test APP will allow people to take flexible antigen self-tests – at any time and in any place – and will even validate the antigen self-test results to ensure reliable, scalable and inexpensive testing.

Step 1:

Identity Check

Identification of the test person with valid picture ID

Biometric profile is created encrypted on the smartphone

Stored profile identifies user for each test and for each presentation of a test result

Step 2:

Certified antigen self-tests

Digital process identifies test and ensures certified test is used

Encrypted serial code on test cassette uniquely assigns test to a person

Step 3:


Video training is available upfront

App guides through test with detailed step-by-step instructions

Step 4:

Verified evidence

Test results enable verified and tamper-proof detection

Transfer of the result to other Apps via interface only after explicit approval of the user

Monitoring of the proper execution of the test is carried out via AI and AR

If test was not proper performed the test is documented as cancelled and cannot be used again

Step 5:


If the test result is positive, a note appears indicating the necessary follow-up activities

Negative test result is available immediately

Result can be presented to human or machine auditor

Maximum Data Protection

The antigen self-test procedure can be implemented in compliance with the highest data protection standards.
Local Storage
Personal data is only stored and encrypted on the App locally on the smartphone (IOS & Android).
Tamper-proof Code
A hash of the encrypted personal data is stored in the backend on the smartphone. It is used to verify the integrity of the locally stored personal data on the smartphone. If only one character changes the hash cannot validate the data anymore.
Secured In-App data
The in-App data can only get accessed after successful login in the smartphone and app.
In case of loss
Loss of the phone and loss of the App leads to a loss of the test data.
